Modern engineering projects face increasingly stringent demands for both material performance and environmental compatibility. Particularly in water conservancy, transportation, and landscape projects, constructing stable, durable, and eco-friendly protective structures remains a persistent challenge for engineers. While traditional concrete structures offer strength, they often lack flexibility and may have adverse environmental impacts. Meanwhile, seemingly simple gabion systems hold remarkable potential to transform engineering approaches.

Developed in accordance with the European Technical Assessment (EOTA) and EU Regulation No 305/2011, hexagonal mesh reinforced retaining walls (Gabion Boxes) and ecological mattresses meet rigorous technical specifications. This certification ensures each product undergoes thorough scientific evaluation to guarantee expected performance and durability in practical applications.

These are variable-sized containers made from double-twisted metal wire mesh with uniformly divided internal cells. On-site, these containers are interconnected and filled with stones to form highly flexible, permeable, and integrated structures. Applications include:

• Retaining walls and seawalls
• River channel linings
• Slope protection
• Erosion control weirs

Similar in construction to gabion boxes but with relatively lower height and typically smaller mesh openings, these are primarily used for riverbank protection and channel linings. Their exceptional flexibility and permeability effectively resist water flow erosion.

Included within the assessment scope, these provide flexible solutions for specific scenarios.

All products utilize high-quality double-twisted metal wire mesh with non-precious metal (such as zinc) coated steel wire for superior corrosion resistance. For more demanding applications, additional organic coatings like PVC, PE, or PA6 can be applied over the zinc coating, significantly extending service life.

Installation offers multiple reliable connection methods:

• Manual binding: Using binding wire of equal or smaller diameter than the mesh wire, suitable for complex terrains
• Spiral connection: Securely locks adjacent units using spiral fasteners along edge wires
• C-ring/clip connection: Enables rapid assembly with specialized tools, maintaining connections at up to 200mm spacing

Hexagonal mesh reinforced structures demonstrate remarkable potential across multiple engineering disciplines:

• Soil reinforcement: Provides exceptional shear strength against landslides and erosion
• Hydraulic engineering: Effective for river management, reservoir bank protection, and dam reinforcement
• Transportation infrastructure: Enhances safety and durability for bridge abutments, retaining walls, and roadbed protection
• Ecological restoration: Permeable and vegetation-friendly design promotes biodiversity in green slopes and landscape walls
• Noise barriers: Serves as structural framework for sound-absorbing materials in traffic noise control

European standards evaluate material durability across different corrosion environments (C2 to C3). Zinc-coated products in dry C2 environments achieve 25-year lifespans, while C3 environments maintain 10-year performance. Additional organic coatings primarily provide supplementary protection, with zinc remaining the primary durability factor.

The assessment protocol specifies rigorous testing methods for critical performance indicators:

• Mechanical properties: Mesh size, wire diameter, tensile strength, elongation, and connection integrity
• Corrosion resistance: Zinc coating type, mass/area ratio, adhesion, and organic coating specifications
• Dimensional accuracy: Product dimensions and connection component precision
• Acoustic performance (optional): Airborne sound insulation and absorption characteristics for noise barriers

All evaluations strictly follow European standards (EN 10223-3, EN 10218-1/2, EN 10244-2, EN 10245 series) to ensure scientific validity and comparability.

Manufacturers implement stringent Factory Production Control (FPC) systems covering raw material inspection, production monitoring, and final product testing. Certification bodies conduct ongoing supervision to verify compliance with standards for mesh dimensions, wire specifications, coating quality, tensile strength, and connection durability.
